This course describe the STM32 WB architecture and practical examples

Objectives

  • Understand dual-core WB: CM4 (app) + CM0+ (wireless coprocessor).
  • Install/verify FUS and wireless stack images (BLE/Thread/Zigbee).
  • Use IPCC/TL/ACI to drive the stack; handle events and errors.
  • Build BLE GAP/GATT apps (services, security, notifications).
  • Bring up Thread or Zigbee nodes (commissioning, messaging).
  • Explore multiprotocol (BLE + 802.15.4) basics and constraints.
  • Apply low-power with RF, measure impact, and set TX power.
  • Prepare OTA/DFU, NVM/bonding data, and a production checklist.
  • Theoretical course
    • PDF material in English (printed for face-to-face); online over Teams.
    • Trainer assistance throughout.
  • Practical activities (40-50% of duration)
    • Code examples, exercises and solutions.
    • Remote: one online Linux PC per trainee, with emulated or physical board as needed.
    • Face-to-face / on-site: one PC (one per two beyond six trainees), target board and install manual as needed.
  • Downloadable preconfigured VM to redo the labs afterwards.
  • Each session starts with a trainee check-in.
  • Any embedded systems engineer or technician with the above prerequisites.
  • Prerequisites are checked before the training.
  • Progress is assessed by the trainer through the practical exercises, and by quizzes for sections without exercises.
  • Each trainee receives a completion certificate.
  • If a prerequisite gap appears, alternative or additional training is offered.
